Big checkin that adds a number of features and makes some changes:

* Updated jQuery to 1.2.6
* Add jQuery UI 1.6b for interface effects as needed
    * 'Smoothness' theme from ThemeRoller.com added.
* Clean up 'Filter' dialog on Ticket List, long way to go still.
    * Uses tabs to save a query or load a saved query
    * Lots of misuse of space here, can be cleaned up somewhat still.
* Add ability for users to save filters/queries
    * Saved queries can be shared, so other users can use them
    * Users can run saved queries instead of re-filtering
    * Filter mechanism in Ticket List had to be reworked significantly
* Merged 3rd party licenses into LICENSE.3RDPARTY
* Updated messages files for EN locale

To update, ensure you run './manage.py syncdb' to add the SavedSearch
table.
